Abstract
VISOLUX Elektronik GmbH is one of Germany’s leading companies for development, production and marketing of a wide variety of non-contact sensor systems. VISOLUX is a manufacturer with high quality level and excellent performance. The main business is in the sector of opto-sensors. The company sells ist products world-wide. Our customers mostly are OEM’s, operating in the markets: Industrial Automation, Material-Handling, Move and Traffic, Safety. The products are used in automation of industrial applications like folding machines, filling machines and others.
The aim of the application experiment is to start using Mixed-Signal ASIC technology, to improve competitiveness, to overcome barriers which have prevented the company to adopt new technologies, to enable the company to replicate the experiment and to gain knowledge and experience in the new technology.
The results are to see in a new improved product and in the increase of certain know-how. The existing product is a photo electronic sensor. The used technology is standard assembly of discrete components on PCB’s. The existing products are too expensive to manufacture and not longer competitive in their market:
With the new developed Opto-Asic a cost- reduction and size-reduction with more than 50 % is possible. But the use of a special transparent package is absolutely necessary, which is not a standard-package.
The size-ratio for the mixed signal ASIC are about 25 % for the photodiode, 55 % digital and 20 % analogue.
This AE has it’s general benefits in realising of innovation, economically we expect increased profits. The forecast for the payback period will be approx. 16 month and the estimated ROI will be about 1700% for a 5-year period.
The increment in capability is the decrease of the ”time to market”.
The costs and duration of the AE have been approx. 77 K¤ and the time of the project was 10 months to come to functional prototypes.

Detailed information

You can also benefit from microelectronics

??? technology provided ??? with the means of improving its products and enhancing its market position. You can also achieve significant benefits by acquiring the right microelectronics technology and utilising it in your product or manufacturing process. You can get help from FUSE to realise this.

FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.

FUSE provides you with:

  • Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
  • Local training and expert support to plan your innovation realistically and help you conduct your project successfully.

Further information and support relating to this and other demonstrators can be obtained from the addresses below.
